MI splitting countyborders to a coastlayer.
Hello members. I am trying to split borders to a coastlayer, so no border is visible at sea. My coast is a polygon layer (many, many polygons witch reprecent a coastal contour or a shore if you like. It goes a few km out to sea also) and my borders are converted polylines (from region). Right now im setting the borders as target. I select all the coast-polygons that the border intersect and do a split. Then i remove the line-elements (from the border-layer) at sea. (Hope this description gives sense, and i am thinking i'm doing this the hard way) Two questions: Are there a easier way to split the borders (with overlay split or similar operations). Should i combine all polygons in the coast layer to one big polygon for easier handeling.(Big operation -10.000 polygons) And are there a split option in mapinfo on a single line-layer??(splitting at a node and creating two lines instead of one continuious line) Regards Kjartan Greiff Bravida Geomatikk As Steinkjer, Norway -- To unsubscribe from this list, send e-mail to [EMAIL PROTECTED] and put "unsubscribe MAPINFO-L" in the message body, or contact [EMAIL PROTECTED]

greeting members. I have a problem during querying tables. I get the message "can not open table". A memory problem i wondered. Its a table with 250.000 records ( and i have recently done queryies on tables with a millon records with no problem). On a query that i know returns few records, lets say about 20.000 it goes ok, but a query that should return about 200.000 records goes "ad undas". I've done boot on the hardware and some memoryadjustments, but still the same problem. (enough space on the disk too. Im pretty new to MI and are there some things in the sw that i should check out according to this problem. (What about temporary files or somethiing like that). Any hints or tips would be helpful Regards Kjartan Greiff Selnes Bravida Geomatikk As Steinkjer- Norway -- To unsubscribe from this list, send e-mail to [EMAIL PROTECTED] and put "unsubscribe MAPINFO-L" in the message body, or contact [EMAIL PROTECTED]
MI Query a textfield
Dear List. I have a table witch contains a text-coloumn(citynames). Some cities occours several times in the coloumn at approximately the same location I'm trying to query this table to get unique citynames in the column (avoid duplicate names)with: select columns: * >From tables: tablename Group by columns: cityname I get a result witch looks alright in a browser, but i noticed that no points where selected from the original mapper(table). I saved the query as a table and opened it. It will not open the file in a mapper but only in a browser!!!. For the l... of G.. why!! Hope some of you gurus can help me out.

MI Geocode
Hi list. I have a question that may be a bit off target regarding to MapInfo-competance but i am a bit desperate right now... I have this problem to import the tables in a huge oraclebase to MapInfo (via Access). Any ODBC-call from Access goes wrong. But there is a CD with a dump of the oracle data with the file-extension *.dmp. Does anyone have experience retriving such files?? Any response would be useful Regards Kjartan Bravida Geomatikk As Norway -- To unsubscribe from this list, send e-mail to [EMAIL PROTECTED] and put "unsubscribe MAPINFO-L" in the message body, or contact [EMAIL PROTECTED]
MI Graphical elements
Hi list I have converted a set of data from a norwegian format (SOSI) to MapInfo-format. These data contains among other things the graphical elements (directly translated); "circle" and "bows" witch is represented by two points(bow) or one point(center,circle) and a radius that describes the size of the element. My question to you is : Does MapInfo(MI) reconize these elements or will MI just operate on lines,points,polygons and text. And if MI not reconize it, how does it then represent f.ex. the bow? As short lines or longer lines with sequential coordinates or what ?? You see, i will use the data in another application whitch does not reconize bows and circles, so in my case it is actually best if MI represent the bows as a type of lines.......
